Vapor-tight lighting fixture
First Claim
1. A vapor-tight luminaire comprising:
- a vapor-tight lower housing defining a continuous and unbroken sealed tubular lens having a pair of end cap structures, the lower housing removably supporting a lamp assembly;
an upper housing separated from the lower housing along an elongated length thereof between the end cap structures, the upper housing containing electronics for operating the lamp assembly and being interconnected with line current; and
an interconnecting harness extending along at least one of the end cap structures between the electronics and the lamp assembly.

Abstract
This invention provides a vapor-tight luminaire that maintains a moisture-proof, sealed lower housing for the light-producing lamps (fluorescent lights, LED arrays, etc.) while isolating the electronic components in a separate, upper housing that is spaced apart from, and largely thermally isolated from, the lamps. The lamp housing comprises a unitary non-penetrated tubular lens with one or more removable end caps, sealed by gaskets. The lamp assembly is slidably mounted within the lower housing so that it is readily removable and replaceable with another assembly of the same or different type. The electronics in the upper housing is readily accessible and replaceable by removing a top cover that encloses a three sided channel member. The upper housing is metal and desirably enhances heat exchange with the environment. The two housings are held together by a pair of opposing end cap structures that include a housing end and a removable end cap. The housing end includes an upper plate that is fastened against an adjacent end of the upper housing'"'"'s channel member. This compresses gaskets that stand between the respective ends of the lens and a lower ring on each housing end. The electronics of the upper housing is interconnected via a wiring harness connector to an end connector in on the lamp assembly. The wiring harness passes between the two housings free of penetration of the lens.

31. A vapor-tight luminaire comprising:
-
a vapor tight housing having at least one removable sealed end cap and a unitary sealed tubular lens that transmits light through at least a portion thereof, the housing including a support assembly within its interior; and a lamp assembly constructed and arranged to slidably engage and disengage the support assembly, the support assembly extending through the tubular lens and being attached only at each end cap when the lamp assembly is respectively passed into and out of an end of the housing with the at least one removable end cap removed therefrom. - View Dependent Claims (32, 33, 34, 35, 36)

37. A method for replacing or retrofitting a lamp assembly in a luminaire comprising the steps of:
-
providing (a) a vapor-tight lower housing defining a continuous and unbroken sealed tubular lens having a pair of end cap structures and a lamp assembly contained therein, (b) an upper housing separated from the lower housing along an elongated length thereof between the end cap structures, the upper housing containing electronics for operating the lamp assembly and being interconnected with line current, and (c) an interconnecting harness between the electronics and the lamp assembly; removing an end cap respectively from at least one of the end cap structures to define an end opening in the lower housing; disconnecting the lamp assembly from the interconnecting harness; sliding the lamp assembly through the end opening and out of the lower housing; sliding a replacement lamp assembly through the end opening and into a final position therein; connecting the interconnecting harness to the replacement lamp assembly; and attaching the end cap to the one of the end cap structures to form a vapor-tight seal at the lower housing. - View Dependent Claims (38)
